Wherever you're going, whether it's on a trek or on the job, flexibility and reliability are key. Roll top backpacks provide the generosity you need in a bag by giving an adjustable closure depending on how much you pack. Magnetic elastic closures keep your storage secure, and the ballistic nylon is as durable as it gets. Complete with padded shoulder straps and an interior laptop sleeve that fits up to a 17' laptop. Get out there.
